The Australian Bureau of Statistics says it is confident it has the right procedures in place to hold the biggest Census yet, despite lockdowns and COVID-19 outbreaks.
About 75 per cent of Australians are expected to complete the form online but that's not the case for everyone.
Demographers say it is crucial to gather data during a pandemic to determine how Australians' lifestyles have changed over time.
Australia's Census date is August 10.
